GitLab vs Datadog
The short version
- Only GitLab has a free tier, so it costs nothing to try first.
- Each has a real cost: GitLab baseline requires 8 vCPU and 16 GB RAM for single-node installations; resource-intensive; Datadog consumption-based pricing model makes costs hard to predict and can scale quickly
- They diverge on capability: GitLab covers Git repository management, Datadog covers Infrastructure monitoring.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
GitLab
- Baseline requires 8 vCPU and 16 GB RAM for single-node installations; resource-intensive
- PostgreSQL is mandatory; no support for alternative databases
- Redis or Valkey cache required; adds infrastructure complexity
- High-availability deployments require inter-node latency below 5 ms; difficult to achieve across geographically distributed sites
- Requires self-hosting and maintenance; GitLab.com SaaS only available to GitLab team members for administration
Datadog
- Consumption-based pricing model makes costs hard to predict and can scale quickly
- Add-on modules significantly increase costs: custom metrics, indexed spans, extended retention
- No free tier for production monitoring
- High costs for organizations with large amounts of log data or high-cardinality metrics
